EnBloc Resection of a Chordoma of the Thoracic Spine by "L"-Shaped Osteotomy for Spinal Canal Preservation.

: EnBloc resections of bone tumors of the spine are very demanding as the target to achieve a tumor-free margin specimen (sometimes impossible due to the extracompartimental tumor extension) is sometimes conflicting with the integrity of neurological functions and spine stability. : The surgical treatment of a huge multi-level chordoma of the thoracic spine with unusual extension is reported. Anteriorly, the tumor widely invaded the mediastinum and displaced the aorta; on the left side, it expanded in the subpleuric region; posteriorly, it was uncommonly distant 13 mm from the posterior wall.

Effects of Four Sulfonate-Containing Additives and Hydroxyethyl Cellulose on the Properties of Electrolytic Copper Foils.

Ultrathin electrolytic copper foils with a thickness of 6 μm were prepared by a test machine using copper sulfate electrolyte with gelatin, hydroxyethyl cellulose (HEC), and sulfonic acid-containing organics as additives. The effects of four sulfonic acid-containing organic additives, sodium 3-mercaptopropanesulfonate (MPS), bis-(sodium sulfopropyl)-disulfide (SPS), sodium 3-[[(dimethylamino)thioxomethyl]thio]propanesulfonate (DPS), and sodium 3-((4,5-dihydrothiazol-2-yl)thio)propane-1-sulfonate (TPS), on the physical property of copper foils were investigated. The results show that all these additives can effectively improve the gloss and tensile strength of electrolytic copper foil, and the texture coefficients of Cu(111) selectivity increase.

Effects of Pre-Deformation in Corrosion Fatigue Crack Growth of Al-Mg-Zn Alloy.

This study investigated the effect of pre-deformation on the corrosion fatigue crack propagation (CFCG) of Al-Mg-Zn alloy in a corrosive environment. Tensile tests at different pre-deformation levels and molecular dynamics simulations analyzed changes in dislocation density. Corrosion fatigue experiments were conducted in a 3.

Comparative Mitogenomics in the Genus (Coleoptera: Cerambycidae) and Its Phylogenetic Implications.

Chevrolat, 1863, one of the most species-rich genera of Clytini, comprises 36 subgenera and 302 species/subspecies, with some species being of significant economic importance. To assess the monophyly and subgeneric system of this genus, we newly obtained mitochondrial genomic data from 21 species of via high-throughput sequencing and reconstructed the phylogeny of this genus using ML and BI methods. The mitochondrial genomes of all sequenced species were found to comprise 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs), and one non-coding region (control region, CR), reflecting a highly conserved gene arrangement.

Effect of Praziquantel on Preventing Delayed Infection of in Buffaloes and Goats.

Schistosomiasis, caused by , continues to pose a major public health threat in East Asia, with an estimated 71 million people at risk of infection. Domestic animals, especially buffaloes and goats, serve as important reservoir hosts, facilitating the transmission of the parasite to humans. While praziquantel (PZQ) is the first-line treatment for schistosomiasis due to its broad-spectrum efficacy against adult schistosomes, its prophylactic potential is less explored.
